Abstract
BACKGROUND We assess if state-issued nonpharmaceutical interventions (NPIs) are associated with reduced rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as measured through anti-nucleocapsid (anti-N) seroprevalence, a proxy for cumulative prior infection that distinguishes seropositivity from vaccination. METHODS Monthly anti-N seroprevalence during 1 August 2020 to 30 March 2021 was estimated using a nationwide blood donor serosurvey. Using multivariable logistic regression models, we measured the association of seropositivity and state-issued, county-specific NPIs for mask mandates, gathering bans, and bar closures. RESULTS Compared with individuals living in a county with all three NPIs in place, the odds of having anti-N antibodies were 2.2 (95% confidence interval [CI]: 2.0-2.3) times higher for people living in a county that did not have any of the 3 NPIs, 1.6 (95% CI: 1.5-1.7) times higher for people living in a county that only had a mask mandate and gathering ban policy, and 1.4 (95% CI: 1.3-1.5) times higher for people living in a county that had only a mask mandate. CONCLUSIONS Consistent with studies assessing NPIs relative to COVID-19 incidence and mortality, the presence of NPIs were associated with lower SARS-CoV-2 seroprevalence indicating lower rates of cumulative infections. Multiple NPIs are likely more effective than single NPIs.

Abstract
Preventing mortality in intensive care units (ICUs) has been a top priority in American hospitals. Predictive modeling has been shown to be effective in prediction of mortality based upon data from patients' past medical histories from electronic health records (EHRs). Furthermore, visualization of timeline events is imperative in the ICU setting in order to quickly identify trends in patient histories that may lead to mortality. With the increasing adoption of EHRs, a wealth of medical data is becoming increasingly available for secondary uses such as data exploration and predictive modeling. While data exploration and predictive modeling are useful for finding risk factors in ICU patients, the process is time consuming and requires a high level of computer programming ability. We propose explICU, a web service that hosts EHR data, displays timelines of patient events based upon user-specified preferences, performs predictive modeling in the back end, and displays results to the user via intuitive, interactive visualizations.

Abstract
Goal line officials (GLO) are exposed to extreme environmental conditions when employed to officiate in professional European soccer cup competitions. The present study aimed to investigate the effect of such environments on GLO decision-making ability. Thirteen male participants were exposed to three conditions: cold (-5°C, 50% relative humidity (RH)); temperate (18°C, 50% RH); and hot (30°C, 50% RH) for 90 min per condition, with a 15 min half-time break after 45 min. Decision-making ability was assessed throughout the 90 min exposure. Core and skin temperatures were recorded throughout. Decision making was improved during exposure to the temperate condition when compared with the cold (mean difference = 12.5%; 95% CI = 1.1%, 23.9%; P = 0.031). Regression analysis indicated that as skin temperature increases so does decision-making ability. Exposure to cold conditions diminished the decision-making ability of GLO.

Abstract
Soccer referees enforce the laws of the game and the decisions they make can directly affect match results. Fixtures within European competitions take place in climatic conditions that are often challenging (e.g., Moscow ~ −5°C, Madrid ~30°C). Effects of these temperatures on player performance are well-documented; however, little is known how this environmental stress may impair cognitive performance of soccer referees and if so, whether exercise exasperates this. The present study aims to investigate the effect of cold [COLD; −5°C, 40% relative humidity (RH)], hot (HOT; 30°C, 40% RH) and temperate (CONT; 18°C, 40% RH) conditions on decision making during soccer specific exercise. On separate occasions within each condition, 13 physically active males; either semi-professional referees or semi-professional soccer players completed three 90 min intermittent treadmill protocols that simulated match play, interspersed with 4 computer delivered cognitive tests to measure vigilance and dual task capacity. Core and skin temperature, heart rate, rating of perceived exertion (RPE) and thermal sensation (TS) were recorded throughout the protocol. There was no significant difference between conditions for decision making in either the dual task (interaction effects: FALSE p = 0.46; MISSED p = 0.72; TRACKING p = 0.22) or vigilance assessments (interaction effects: FALSE p = 0.31; HIT p = 0.15; MISSED p = 0.17) despite significant differences in measured physiological variables (skin temperature: HOT vs. CONT 95% CI = 2.6 to 3.9, p < 0.001; HOT vs. COLD 95% CI = 6.6 to 9.0, p < 0.001; CONT vs. COLD 95% CI = 3.4 to 5.7, p < 0.01). It is hypothesized that the lack of difference observed in decision making ability between conditions was due to the exercise protocol used, as it may not have elicited an appropriate and valid soccer specific internal load to alter cognitive functioning.

Abstract
BACKGROUND Pitrakinra is a recombinant protein derived from human interleukin-4 (IL-4) that binds to IL-4Ralpha and acts as a competitive antagonist of IL-4 and IL-13. The studies reported here compare the dose-ranging effects of pitrakinra on allergen-induced airway hyperresponsiveness (AHR) and airway eosinophilia when administered subcutaneously (s.c.) or by inhalation to the Ascaris suum-sensitive cynomolgus monkey for the purpose of elucidating the primary site of pitrakinra's anti-asthmatic action. METHODS Airway responsiveness to inhaled methacholine and bronchoalveolar lavage cell composition was determined before and after three allergen exposures with a 1-week course of twice-daily (b.i.d.) s.c. or inhaled pitrakinra or placebo treatment. RESULTS Treatment with s.c. pitrakinra significantly reduced allergen-induced AHR, with a maximum effect of a 2.8- to 3.8-fold increase in methacholine PC(100) relative to control (P < 0.05) observed at b.i.d. s.c. doses of 0.05-0.5 mg/kg. Inhaled pitrakinra also significantly reduced AHR with a similar maximum effect of a 2.8- to 3.2-fold increase in methacholine PC(100) relative to control (P < 0.05) at nominal b.i.d. doses of 3-100 mg. The maximal effect on AHR following inhalation was observed at a plasma concentration which exhibited no efficacy via the subcutaneous route. The effect of pitrakinra on lung eosinophilia was not statistically significant following either route of administration, although lung eosinophil count was reduced in all studies relative to control. CONCLUSION Local administration of pitrakinra to the lung is sufficient to inhibit AHR, one of the cardinal features of asthma, indicating the therapeutic potential of inhaled pitrakinra in the treatment of atopic asthma.

Abstract
We describe the first cases of familial pulmonary capillary hemangiomatosis, a disorder in which capillaries in the lungs proliferate. Three siblings died from primary pulmonary hypertension. One developed pulmonary congestion preterminally after vasodilator treatment. The inheritance pattern seems autosomal recessive. Lung specimens obtained in two siblings showed extensive pulmonary capillary hemangiomatosis, with normal capillaries proliferating into veins and alveoli. Including our patients, four of the nine patients with pulmonary capillary hemangiomatosis have presented with the clinical picture of primary pulmonary hypertension. Thus, pulmonary capillary hemangiomatosis should be considered as a histologic pattern of primary pulmonary hypertension. Most other cases of pulmonary capillary hemangiomatosis have been similar to pulmonary veno-occlusive disease. Recently, disorders involving the proliferation of cytologically normal capillaries have been termed angiogenic diseases. Pulmonary capillary hemangiomatosis may be an angiogenic disease.

Abstract
Two sisters born to consanguineous parents had a syndrome of short stature, acrocephaly, hypertelorism, proptosis, ptosis, down-slanting palpebral fissures, high nose bridge and anteverted nares, short philtrum, cleft palate, micrognathia, abnormal external ears, preauricular pits, sensorineural and conductive deafness, proximally placed first toes and digitalized thumbs, bulbous digits, metatarsus adductus, and pectus excavatum. Radiological abnormalities included craniosynostosis, increased mandibular angle and antegonial notching of mandible; hypoplastic first metacarpals and metatarsals; hypoplastic distal phalanges; partial duplication of the distal phalanx of the thumb; malformed malleus and incus; tall lumbar vertebrae, increased interpedicular distance, and posterior scalloping; flared iliac wings, narrow supraacetabular regions, acetabular "dysplasia," and coxa valga. Autosomal recessive inheritance is suggested.

Abstract
Ninety-one families of Alzheimer patients were studied to determine the proportion of familial cases, to obtain pedigrees for the analysis of the mode of inheritance, and to look for clinical differences between the familial and the nonfamilial cases. The diagnosis was confirmed by autopsy in 26 cases. Thirty-nine cases (43%) were familial, which is defined as more than one case in the family. Our interpretation of the pedigree data is that Alzheimer's disease is etiologically heterogeneous: it may be genetic or sporadic. In the familial type we think that the disease is inherited as an autosomal dominant, with a wide range of age of onset within a family. In one-third of these families the gene is not expressed until over age 70. No clinical differences were found between the familial and the sporadic groups.

Abstract
Two sisters with premature menopause and a small deletion of the long arm of one of their X chromosomes [del (X)(pter----q26.3:)] were investigated with polymorphic DNA probes near the breakpoint. The deleted chromosome retained the factor IX (F9) locus and the loci DXS51 (52A) and DXS100 (pX45h), which are proximal to F9. However, the factor VIII (F8) locus was not present, nor were two loci tightly linked to this locus, DXS52 (St14) and DXS15 (DX13). This deletion refines the location of the F9 locus to Xq26 or to the interface Xq26/Xq27, thus placing it more proximally than has been previously reported. The DNA obtained from these patients should be valuable in the mapping of future probes derived from this region of the X chromosome.

Abstract
The radiological findings in two patients with the Proteus syndrome are described. Features in our two cases not previously mentioned or stressed include vertebral dysplasia and enlargement (megaspondylodysplasia), bilateral genu valgum, recurrent after surgery and intraabdominal and mesenteric lipomatosis. Emergency laparotomy was performed on the first patient who had a twisted necrotic portion of mesenteric fat. Macrodactyly, skeletal muscle atrophy and subcutaneous fat accumulation in the abdominal wall were present in both. In addition the second patient was mentally retarded and had frontal bony prominence of skull. Computed tomography was used for the specific diagnosis of the lipomatous tissues in both patients.

Abstract
Eleven Y-specific DNA probes hybridizing with DNA from one or more 46,XX males were isolated from a recombinant phage DNA library constructed from flow sorted human Y chromosomes. Two probes hybridized with DNA from nine out of eleven, i.e. greater than 80% of these 46,XX males. The relative frequency of hybridization of the probes in the 46,XX males and in a 46,X,dic(Y) female, together with in situ hybridization data, allowed mapping of the probes on Yp in relation to a putative testis determining locus. Several of those probes were also absent in a 46,XY female, further refining a model for ordering the probes on Yp. The DNA of one XX male hybridized both with probes from Yp and probes from proximal Yq (excluding the pericentral region). This suggests that complex translocations may occur into the DNA of 46,XX males that involve not only parts of Yp but also parts of Yq.

Abstract
Several investigators have suggested that the Marshall syndrome and the Weaver syndrome are one entity because of some phenotypic overlap. This paper reviews the findings in nine additional patients with the Marshall syndrome and concludes that the syndromes are two distinct entities. In the Marshall syndrome there is a characteristic facies, failure to thrive in terms of height, weight, and psychomotor development, and early death. In the Weaver syndome the infants thrive too well: weight and heights are much above normal. They also have increased bifrontal diameters, hypertonia, prominent finger pads, and thin, deep-set nails, and the face is quite different from the Marshall facies.

Abstract
Bilateral and unilateral renal agenesis may be expressions of single dominant gene. Chromosome abnormalities may be present and the renal agenesis may be part of a syndrome of multiple abnormalities. Apparently normal relatives of affected individuals should be screened by intravenous pyelography before genetic counselling given.

Abstract
A woman with the autosomal dominant syndrome of preauricular pits, cervical fistulae, and partial deafness gave birth to two children with preauricular pits and severe renal dysgenesis. The facies had some features of the Potter facies of renal agenesis. One child died soon after birth because of pneumothorax and immature development of the lungs. We suggest that all infants with renal agenesis or dysgenesis be examined for preauricular pits because of the high recurrence risk of renal anomalies in families with this syndrome.

Abstract
A family is described in which two male infants have microcephaly, abnormal ears, anti-mongoloid slant, small mouth, cleft palate, flexed overlapping fingers with syndactyly of digits three and four, syndactyly of the second to the fifth toes, and normal karyotype. This seems to be a new syndrome.

Abstract
Histological study of the temporal bones of an infant with the preauricular pit, cervical fistula, hearing loss syndrome revealed abnormalities in the middle ear, the vestibular system, and the cochlea. There is a gross bilateral abnormality in the form and relationship of the middle ear spaces, the middle cranial fossa and the inner ear. The horizontal canal lacks ampulla and crista; the posterior canal terminates a short distance from the ampulla. The cochlear cavity is approximately four fifths of normal size. The modiolus of the cochlea shows minor abnormalities. Spiral ganglion cells and peripheral nerve fibers are present in all coils, but are below normal in population in the basal and apical coils. The stria vascularis is slightly deformed and partly atrophic in the upper apical coil. An occasional concretion is present in the base of the stria vascularis in the middle and apical coils.
